Description

TECHNICAL FIELD

The present disclosure relates to the field of communication technologies, and in particular to a communication method and related devices for partitioning precoding resource block groups on an initial bandwidth part before obtaining remaining minimum system information.

BACKGROUND

When a User Equipment (UE) accesses a network device or is in an idle state, it needs to read broadcast information. The broadcast information includes remaining minimum system information (RMSI), other system information (OSI), and paging information, etc. Before the UE obtains the RMSI, the UE obtains very few information from the network device, only obtaining physical cell identifier (PCI), timing (or timing sequence), etc. However, the grid partitioning of the precoding resource block groups (PRGs) in the related art is performed from a starting reference point of a current component carrier (CC), thus, before the mobile communication terminal obtains the RMSI, the UE cannot perform grid partitioning according to a PRG partitioning method in the related art, resulting in poor demodulation performance of the resource block (RB). Published document "Remaining details on remaining minimum system information delivery" (R1-1720791) discusses details of RMSI such as CORESET configuration in NR-PBCH, PDCCH monitoring window configuration, the number of transmission blocks and RMSI TTI.

SUMMARY

The invention is set out in the appended set of claims. Embodiments of the present disclosure provide a communication method and related devices, which can solve the problems of poor demodulation performance of the resource block (RB).
In order to solve the above technical problem, the present disclosure is implemented as follows.
In a first aspect, one embodiment of the present disclosure provides a communication method applied to a mobile communication terminal, including:

before obtaining remaining minimum system information (RMSI) transmitted by a network device, partitioning precoding resource block groups (PRGs) on an initial bandwidth part (BWP); and
communicating with the network device on the initial bandwidth part. The partitioning precoding resource block groups (PRGs) on an initial bandwidth part (BWP), includes: after obtaining a synchronization signal and PBCH block (SSB), partitioning the PRGs on the initial bandwidth part from a third target position of RMSI control resource set (CORESET) signaled by the SSB, wherein the third target position is pre-agreed by the protocol

In a second aspect, one embodiment of the present disclosure provides a communication method applied to a network device, including:

a first partitioning module configured to, before obtaining remaining minimum system information (RMSI) transmitted by a network device, partition precoding resource block groups (PRGs) on an initial bandwidth part (BWP);
a first communication module configured to communicate with the network device on the initial bandwidth part. When partitioning precoding resource block groups (PRGs) on an initial bandwidth part (BWP), the first partitioning module is configured to, after obtaining a synchronization signal and PBCH block (SSB), partition the PRGs on the initial bandwidth part from a third target position of RMSI control resource set (CORESET) signaled by the SSB, wherein the third target position is pre-agreed by the protocol.

Referring to FIG. 2, FIG. 2 is a flowchart of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2, the method includes the following steps.
Step 201: before obtaining remaining minimum system information (RMSI) transmitted by a network device, partitioning precoding resource block groups (PRGs) on an initial bandwidth part (BWP).
The communication method provided in one embodiment of the present disclosure is mainly applied to a mobile communication terminal, and is used for controlling communication between the mobile communication terminal and the network device.
Specifically, the network device may broadcast a synchronization signal block (SSB); and after the mobile communication terminal obtains the SSB, based on the SSB, the mobile communication terminal may perform PRG partitioning on an initial bandwidth part indicated by the SSB. It should be noted that the partitioning manner of PRG may be set according to actual needs, for example, the PRG partitioning may be performed according to a position of the SSB, or the PRG partitioning may be performed according to other related information obtained according to the SSB. For example, the SSB carries indication information of the initial bandwidth part, and then the PRGs may be partitioned according to a position of the initial bandwidth part determined by the indication information.
The initial bandwidth part is a bandwidth part defined by the standard, for example, it may be an initial bandwidth part defined by RAN4.
Step 202: communicating with the network device on the initial bandwidth part.
After partitioning the PRG, data or control information may be transmitted with the network device on the initial bandwidth part based on the partitioned PRG.
In this way, in one embodiment of the present disclosure, before obtaining the RMSI transmitted by the network device, the precoding resource block groups (PRGs) are partitioned on the initial bandwidth part. Therefore, the performance of demodulating resource blocks can be improved according to the embodiment of the present disclosure.
It should be noted that, the above RMSI includes indication information, and the indication information is used to indicate component carrier and bandwidth part (BWP) configured by the network device for the mobile communication terminal. The method further includes:
Step 203: after obtaining the RMSI transmitted by the network device, partitioning the PRGs on the BWP from a starting reference point of the component carrier.
Step 204: communicating with the network device on the BWP.
In one embodiment, after obtaining the RMSI transmitted by the network device, partitioning the PRGs on the BWP from the starting reference point of the component carrier is a PRG partitioning rule specified in an existing standard protocol, and specific partitioning modes are not repeated here.
It should be noted that, as shown in FIG. 3, the channel bandwidth of the network device may include up to 16 CCs, the CCs may be discontinuous but may not overlap, and multiple CCs may be activated simultaneously. Each CC contains up to 4 BWPs, the BWPs may overlap each other and may be discontinuous, and only one BWP can be activated in one CC.
In order to better understand the present disclosure, the process of obtaining the RMSI by the mobile communication terminal is described here. Specifically, the mobile communication terminal first obtains the SSB. After obtaining the SSB, the mobile communication terminal demodulates indication information in the SSB to obtain configuration information of RMSI CORESET. The configuration information of the RMSI CORESET includes a position of the RMSI CORESET (or, a position of the initial bandwidth part) and so on. RMSI CORESET information is first received according to the configuration information of the RMSI CORESET. The RMSI CORESET information carries indication information indicating indication information of RMSI PDSCH. After obtaining the indication information of RMSI PDSCH, the RMSI PDSCH is received according to the indication information of the RMSI PDSCH, and then RMSI is received and demodulated on the RMSI PDSCH.
Based on the above process of obtaining the RMSI, before the RMSI is obtained, the mode and time point for partitioning the PRGs may be set according to actual needs, which will be described in detail hereinafter.
In a first implementation mode, the PRG partitioning may be performed according to a position of the SSB. Specifically, the foregoing partitioning precoding resource block groups (PRGs) on an initial bandwidth part, includes:
after obtaining a synchronization signal block (SSB), partitioning the PRGs on the initial bandwidth part from a first target position of the SSB, where the first target position is pre-agreed by the protocol.
The first target position may be any position in the SSB according to the protocol. For example, the first target position may be a highest position or a lowest position in the SSB. Generally, the highest position refers to a highest index position of a sub-carrier in a certain resource block, and the lowest position refers to a lowest index position of a sub-carrier in a certain resource block. In one embodiment, the first target position may be the lowest index position or the highest index position of sub-carriers in the resource block of the SSB.
In a second implementation mode, the PRG partitioning may be performed according to a position of the initial bandwidth part. Specifically, the foregoing partitioning precoding resource block groups (PRGs) on an initial bandwidth part, includes:
partitioning the PRGs on the initial bandwidth part from a second target position of the initial bandwidth part, where the second target position is pre-agreed by the protocol.
The second target position may be any position in the initial bandwidth part according to the protocol. For example, the second target position may be a highest position or a lowest position in the initial bandwidth part. In one embodiment, the second target position may be the lowest index position or the highest index position of sub-carriers in the resource block of the initial bandwidth part.
In a third implementation mode, the PRG partitioning may be performed according to a position of RMSI control resource set (CORESET). Specifically, the foregoing partitioning precoding resource block groups (PRGs) on an initial bandwidth part, includes:
after obtaining a synchronization signal block (SSB), partitioning the PRGs on the initial bandwidth part from a third target position of RMSI CORESET signaled by the SSB, where the third target position is pre-agreed by the protocol.
The third target position may be any position in the RMSI CORESET according to the protocol. For example, the third target position may be a highest position or a lowest position in the RMSI CORESET. In one embodiment, the third target position may be the lowest index position or the highest index position of sub-carriers in the resource block of the RMSI CORESET.
In a fourth implementation mode, the PRG partitioning may be performed according to a position of RMSI physical downlink shared channel (PDSCH). Specifically, the foregoing partitioning precoding resource block groups (PRGs) on an initial bandwidth part, includes:
after obtaining RMSI CORESET information, partitioning the PRGs on the initial bandwidth part from a fourth target position of RMSI PDSCH indicated by the RMSI CORESET information, where the fourth target position is pre-agreed by the protocol.
The fourth target position may be any position in the RMSI PDSCH according to the protocol. For example, the fourth target position may be a highest position or a lowest position in the RMSI PDSCH. In one embodiment, the fourth target position may be the lowest index position or the highest index position of sub-carriers in the resource block of the RMSI PDSCH.
It should be noted that the foregoing four implementation modes may be implemented separately after the SSB is obtained, or may be implemented in combination after the SSB is obtained. For example, the foregoing fourth implementation mode may be combined with any one of the first to third implementation modes, that is, before the mobile communication terminal obtains the RMSI, the PRG partitioning is performed twice, i.e., before obtaining the RMSI control resource set information, one PRG partitioning may be performed according to any one of the first to third implementation modes, and then after obtaining the RMSI control resource set information, another PRG partitioning may be performed according to the fourth implementation mode.
Further, it should be noted that, when partitioning PRGs, a size of each partitioned PRG is equal to a value of a physical resource block bundle size (PRB bundle size). The physical resource block bundle size is used to indicate a granularity of bundle of received resources in the frequency domain estimated by the mobile communication terminal. The physical resource block bundle size may be pre-agreed by the protocol or may be configured by the network device, which is not further limited here.
It should be noted that various optional embodiments described in the embodiments of the present disclosure may be implemented in combination with each other, or may be implemented separately, which is not limited in the embodiments of the present disclosure.
Referring to FIG. 4, one embodiment of the present disclosure further provides a communication method. As shown in FIG. 4, the communication method includes the following steps.
Step 401: before a mobile communication terminal obtains remaining minimum system information (RMSI) transmitted by the network device, partitioning precoding resource block groups (PRGs) on an initial bandwidth part (BWP).
The communication method provided in one embodiment of the present disclosure is mainly applied to the network device, and is used for controlling communication between the mobile communication terminal and the network device.
Specifically, the network device may broadcast a synchronization signal block (SSB); and after the mobile communication terminal obtains the SSB, based on the SSB, the mobile communication terminal may perform PRG partitioning on an initial bandwidth part indicated by the SSB. It should be noted that the partitioning manner of PRG may be set according to actual needs, for example, the PRG partitioning may be performed according to a position of the SSB, or the PRG partitioning may be performed according to other related information obtained according to the SSB. For example, the SSB carries indication information of the initial bandwidth part, and then the PRGs may be partitioned according to a position of the initial bandwidth part determined by the indication information.
The initial bandwidth part is a bandwidth part defined by the standard, for example, it may be an initial bandwidth part defined by RAN4.
Step 402: communicating with the mobile communication terminal on the initial bandwidth part.
After partitioning the PRG, data or control information may be transmitted with the network device on the initial bandwidth part based on the partitioned PRG.
In this way, in one embodiment of the present disclosure, before obtaining the RMSI transmitted by the network device, the precoding resource block groups (PRGs) are partitioned on the initial bandwidth part. Therefore, the performance of demodulating resource blocks can be improved according to the embodiment of the present disclosure.
It should be noted that, the above RMSI includes indication information, and the indication information is used to indicate component carrier and bandwidth part (BWP) configured by the network device for the mobile communication terminal. The method further includes:

Step 403: after the mobile communication terminal obtains the RMSI transmitted by the network device, partitioning the PRGs on the BWP from a starting reference point of the component carrier.
Step 404: communicating with the mobile communication terminal on the BWP.

Each CC contains up to 4 BWPs, the BWPs may overlap each other and may be discontinuous, and only one BWP can be activated in one CC.

The configuration information of the RMSI CORESET includes a position of the RMSI CORESET (or, a position of the initial bandwidth part) and so on. RMSI CORESET information is first received according to the configuration information of the RMSI CORESET. The RMSI CORESET information carries indication information indicating indication information of RMSI PDSCH. After obtaining the indication information of RMSI PDSCH, the RMSI PDSCH is received according to the indication information of the RMSI PDSCH, and then RMSI is received and demodulated on the RMSI PDSCH.
Based on the above process of obtaining the RMSI, before the RMSI is obtained, the mode and time point for partitioning the PRGs may be set according to actual needs, which will be described in detail hereinafter.

Generally, the highest position refers to a highest index position of a sub-carrier in a certain resource block, and the lowest position refers to a lowest index position of a sub-carrier in a certain resource block. In one embodiment, the first target position may be the lowest index position or the highest index position of sub-carriers in the resource block of the SSB.
